In the 1970s, Gilder established himself as a critic of feminism and government welfare policies, arguing that they eroded the "sexual constitution" that civilized and socialized men in the roles of fathers and providers. In the 1990s, he became an enthusiastic evangelist of technology and the Internet by several books and his newsletter, the Gilder Technology Report. He is also known as the chairman of George Gilder Fund Management, LLC.

He spent most of his childhood with his mother, Anne Spring (Alsop), and his stepfather, Gilder Palmer, on a dairy farm in Tyringham, Massachusetts. David Rockefeller, a college roommate of his father, was deeply involved with his upbringing.[2]

With his college roommate, Bruce Chapman, he wrote an attack on the anti-intellectual policies of the 1964 Republican presidential candidate Barry Goldwater, The Party That Lost Its Head (1966). He later recanted this attack: "The far Right – the same men I dismissed as extremists in my youth – turned out to know far more than I did. At least the 'right-wing extremists,' as I confidently called them, were right on almost every major policy issue from welfare to Vietnam to Keynesian economics and defense – while I, in my Neo-Conservative sophistication, was nearly always wrong."[5]

Inspired by Wanniski and by the works of free-market economists like Milton Friedman and Friedrich Hayek and novelist Ayn Rand,[6] Gilder wrote a book extending the ideas of his Visible Man (1978) into the realm of economics, to balance his theory of poverty with a theory of wealth.[7] The book, published as the best-selling Wealth and Poverty in 1981, communicated the ideas of supply-side economics to a wide audience in the United States and the world.[8]

Gilder also contributed to the development of supply-side economics when he served as Chairman of the Lehrman Institute's Economic Roundtable, as Program Director for the Manhattan Institute, and as a frequent contributor to Laffer's economic reports and the editorial page of The Wall Street Journal.[9]

The first mention of the word "Digerati" on USENET occurred in 1992 and referred to an article by Gilder in Upside magazine. His other books include Life After Television, a 1990 book that predicted microchip "telecomputers" connected by fiberoptic cable would make broadcast-model television obsolete. The book was also notable for being published by the Federal Express company and featuring full-page advertisements for that company on every fifth page.[10]

Gilder wrote the books Microcosm, about Carver Mead and the CMOSmicrochip revolution; Telecosm, about the promise of fiber optics; and his latest, The Silicon Eye, about the Foveon X3 sensor, a digital camera imager chip. The book cover of the Silicon Eye reads, "How a Silicon Valley Company Aims to Make All Current Computers, Cameras, and Cell Phones Obsolete." The Foveon sensor has not achieved this goal and has not yet been used in cell phones.

Gilder is an active investor in private companies and serves as the chairmen of the advisory board in Israel-based ASOCS that he discovered during his research for Israel Test[3]

Gilder states that men are emotionally/sexually inferior, but as a counterbalance to this existential asymmetry, are often more driven than women in the secular workplace and in creative ventures outside the home because of inborn, biologically determined differences between men and women. Woman creates the baby, as a linchpin of humanity, whereas Man creates as metaphor -- the machine which protects the family from "Nature".

... men are inferior sexually... but they are superior in the workplace and in the great creative ventures outside the family circle. This has been true throughout human history and always will be true. The denial of it is perverse and destructive because men do have an absolutely central role in society that is commensurate with, yet different from, the familial role of women.[11]

Gilder also describes women as "a very physiological consciousness," and asserts that women, because of inborn, biologically determined differences from men, must give up "choice" or the family will be destroyed. Referring to women, Gilder asserted in 1994:

Her sexuality determines her long term goals. As a very physiological consciousness, she knows she can bear and nurture children. She has a central role in the very perpetuation of the species.... The Women's Movement tragically reduces female sexuality to the terms of male sexuality. When this happens, she reduces herself to the male level of recreational sex. Paradoxically, when that happens the woman loses all her power over men and the reverence and respect toward the procreative potential of woman is lost. And that really destroys the family. But if the power of "choice" is given up, the woman actually ascends to a higher level of sexuality and her body attains an almost mystical power over men.[11]

Gilder enjoyed the controversy, appearing on Firing Line to defend himself. He discovered that he had found "a way to arouse the passionate interest of women... it was clear I had reached pay dirt." He decided to make himself into "America's number-one antifeminist".[12]

Gilder moved to New Orleans and worked in the mornings for Ben Toledano, Republican candidate for the United States Senate in 1972 and the party's nominee for mayor of New Orleans in 1970. Also, he wrote Sexual Suicide (1973), revised and reissued as Men and Marriage (1986). He argued that the welfare state and feminism broke the "sexual constitution" that had weaned men off their predatory instinct for sex, war, and the hunt, and it had subordinated them to women as fathers and providers. The book achieved a succès de scandale and Time made Gilder "Male Chauvinist Pig of the Year."[2]

He also stated that divorce "does spread poverty, and bitterness, and feminism, and other problems."[11]

Gilder also wrote Visible Man: A True Story of Post-Racist America (1978, reissued in 1995), which The New York Times described in 1981 as "the account of a talented young black spoiled by the too-ready indolence of America's welfare system."[13]

On "corruption" and "suicide" of Native American and African cultures[edit]

Gilder has asserted that the culture of Native Americans was "corrupt and unsuccessful" and so Native American culture "failed." He describes both black and Native American cultures as "destructive cultures", "tragic failures" and "virtual social suicide." He considered that upholding Native American or black cultures is a "terrible perversion."

Indian culture didn’t fail because it was virtuous. It failed because it was a corrupt and unsuccessful culture. These tribal cultures they [multiculturalists] are trying to import from Africa are tragic failures, too. To uphold these destructive cultures that have been virtual social suicide for the people who live in them is a terrible perversion.[11]

Religion is primary. Unless a culture is aspiring toward the good, the true, and the beautiful, and wants the good and the true, really worships God, it readily worships Satan. If we turn away from God, our culture becomes dominated by "Real Crime Stories" and rap music and other spew.... When the culture becomes corrupt, then the businesses that serve the culture also become corrupt.... Secular culture is in general corrupt, and degraded, and depraved. Because I don't believe in secular culture, I think parochial schools are the only real schools.[11]

Gilder has praised mass immigration as an economic boom in both the US and Israel. Although Gilder's support for mass immigration is admittedly framed by high tech hubs such as Silicon Valley's need for computer programmers, he sees recent American immigration policy as being vital to American prosperity overall going so far as to write in the Wall Street Journal

Without immigration over the last 50 years, I would estimate that U.S. real living standards would be at least 40% lower.[14]

Steve Sailer, a fan of Gilder's books on feminism and race, wrote an 2002 column that the "guess about the net aggregate benefits of immigration to native-born Americans was not only offered without any support evidence whatever, but it actually contradicts a significant economic literature that finds the benefits to be nugatory."

Despite Gilder's defense of mass immigration in the Wall Street Journal, it is unclear whether or not Gilder would object to cuts in low-skilled, mostly third world immigration to the United States, as emphasized by skeptics of recent American immigration policies such as Pat Buchanan.

...Gilder is a nice man – and in person he was curiously undogmatic about immigration. He just hadn't thought about it much. All he wanted, he told an investment conference I was moderating in mid-2000, was an assured supply of cheap computer programmers – other than that, he didn't care. And he thought all immigrants ought to be able to speak English. At this last remark, the entire audience of fat cats, obviously uneasy about our argument, burst into loud applause.[15]

Gilder bought the conservative political monthly magazine The American Spectator from its founder, Emmett Tyrrell, in the summer of 2000, switching the magazine's focus from politics to technology.[16]

Experiencing his own financial problems in 2002,[17] Gilder sold the Spectator back to Tyrrell.[18]

For nearly thirty years, he has lectured internationally on economics, technology, education, and social theory. He has addressed audiences from Washington, DC, to the Vatican, and he has appeared at numerous conferences, public policy events, and media outlets.

Demonstrating his interest in the future of innovation-driven education models, in 2009 Gilder delivered the opening keynote address at the annual EduComm Conference, a nationwide gathering of higher education leaders pursuing breakthrough technologies with the potential to transform the college experience. His annual Telecosm Conference, which he hosts with Steve Forbes, draws technology leaders, entrepreneurs, investors, engineers, and inventors from across the globe.

Today, his lectures often concern his 2009 book, The Israel Test, which deals with the relationship between entrepreneurship, innovation, and geopolitical stability.[citation needed]

After completing Visible Man in the late 1970s Gilder began writing "The Pursuit of Poverty." In early 1981 Basic Books published the result as Wealth and Poverty. It was an analysis of the roots of economic growth. Reviewing it within a month of the inauguration of the Reagan Administration the New York Times reviewer called it "A Guide to Capitalism". It offered, he wrote, "a creed for capitalism worthy of intelligent people."[19] The book was a New York Times bestseller[20] and eventually sold over a million copies.[21]

In Wealth and Poverty Gilder extended the sociological and anthropological analysis of his early books in which he had advocated for the socialization of men into service to women through work and marriage. He wove these sociological themes into the economic policy prescriptions of supply-side economics. The breakup of the nuclear family and the policies of demand-side economics led to poverty. Family and supply-side policies led to wealth.

In reviewing the problems of the immediate past—the inflation, recession, and urban problems of the 1970s—and proposing his supply-side solutions, Gilder argued not just the practical but the moral superiority of supply-side capitalism over the alternatives. "Capitalism begins with giving," he asserted, while New Deal liberalism created moral hazard. It was work, family, and faith that created wealth out of poverty. "It is this supply-side moral vision that underlies all the economic arguments of Wealth and Poverty," he wrote.[22]

In 1994 Gilder asserted that America has no poverty problem, that the real problem is the "moral decay" of the "so-called poor", and that their real need is "Christian teaching from the churches." He calls the poor in America "the so-called poor" who have been "ruined by the overflow of American prosperity", and asserts they have more purchasing power than the middle class in Japan in the 1990s.

What the poor really need is morals...The official poor in America have higher incomes and purchasing power than the middle class in the United States in 1955 or the middle class in Japan today. The so-called "poor" are ruined by the overflow of American prosperity. What they need is Christian teaching from the churches...The poverty line in a rich country like the United States is a meaningless standard. We have no poverty problem strictly speaking, we have a desperate problem of family breakdown and moral decay.[11]

Gilder reveals Israel as a leader of human civilization, technological progress, and scientific advance. Tiny Israel stands behind only the United States in its contributions to the hi-tech economy. Israel has become the world's paramount example of the blessings of freedom.—Amazon book description.

Irving Kristol says, "Everyone talks about 'free enterprise' but no one understands the entrepreneurial basis of economic growth better than George Gilder."

Conservative commentator Rush Limbaugh says, "My friends, it would behoove you to study everything you can get your hands on by George Gilder, a true American genius."[23]

In an interview for National Review, Gilder says the book is about "the cosmic law between success and envy" and states Israel's role as the following:

Western civilization, in part, originated in Israel. Now Israel is a crucial source of invention, military intelligence, and entrepreneurial creativity that may yet save the West. I believe Netanyahu is a Churchillian figure emerging at the perfect time to confront the Jihad.—George Gilder, National Review interview July 2009: "Choosing the Chosen People – Anti-Semitism is essentially hatred of capitalism and excellence."[24]

He, like others at the institute, denies that the Shannon information measure alone provides a good measure for biological information, as that measure ignores the actual function or meaning in the code. Gilder contends that Shannon information theory actually shows that evolution cannot be explained by unintelligent physical causes, because it focuses on "the medium, not the message."[26]
